The invention belongs to the field of building structures, and particularly relates to an assembly type reinforced concrete column construction process based on prefabricated standard assembling pieces. The assembly type reinforced concrete column construction process comprises the following steps of (1) building a three-dimensional grid framework; 2) assembling the prefabricated standard assembling pieces; 3) forming a prefabricated concrete outer layer; and 4) forming the cast-in-place concrete inner layer. On one hand, a series of construction quality problems such as the honeycomb pitted surface of the outer surface of the column in cast-in-place construction are avoided; on the other hand, compared with a traditional assembly type column, is adopted; the single assembling component has the advantages of being small in size, light in self weight, easy to transport, free of large construction machinery and the like, the assembly type column installation workload can be reduced on the premise that the column performance is guaranteed, construction is convenient, the construction efficiency is improved, the application range of the fabricated structure is further expanded, and themarket prospect is wide.
